protocol is described for the reduction of carboxylic acids to primary alcohols using 1,1,3,3-tetramethyldisiloxane (TMDS) and a catalytic amount of Cu(OTf)2. Aliphatic as well as aromatic carboxylic acids are reduced in high selectivity and good yields. TMDS/Cu(OTf)2 has also been found to be an efficient catalytic reducing system for the preparation of symmetrical ethers from carbonyl compounds under
描述了一种使用1,1,3,3-四甲基二硅氧烷(TMDS)和催化量的Cu(OTf)2将羧酸还原为伯醇的方案。脂肪族和芳香族羧酸以高的选择性和良好的产率降低。还发现TMDS / Cu(OTf)2是一种有效的催化还原体系,用于在温和条件下从羰基化合物制备对称醚。
